to study response of bread wheat cv. sardari to row spacing and seeding rate and to determine the desirable seed density under cold rain-fed conditions a two-year study (2008 and 2009) was carried out in qamloo research station located in kurdistan. a strip plot design with three replications was used. four rows spacing including 15, 17.5, 20 and 25 cm as horizontal factor and four seeding rate...

BACKGROUND/AIMS Needle-track seeding is a rare but important complication of diagnostic and therapeutic ultrasound (US)-guided procedures in hepatocellular carcinoma (HCC). We examined the frequency of needle-track seeding after US-guided percutaneous ethanol injection (PEI), fine-needle aspiration biopsy (FNAB), and percutaneous transhepatic biliary drainage (PTBD) in order to determine the ap...

The formal verification of compilers and related programming tools depends crucially on the availability of appropriate mechanized semantics for the source, intermediate and target languages. In this invited talk, I review various forms of operational semantics and their mechanization, based on my experience with the formal verification of the CompCert C compiler. What does this program do, exa...

The following outline summarizes some suggestions about ways in which translation may be mechanized that were worked out by the authors in 19481952. The treatment is not exhaustive, and many modifications in detail would certainly be necessary should the ideas here mooted be put into active operation. It is considered, however, that it would be serviceable to describe the techniques here envisa...

Due to their net warming effect, cirrus clouds play a crucial role in the climate system. A recently proposed climate engineering mechanism (CEM) intends to reduce high cloud cover by seeding cirrus clouds with efficient ice nuclei (IN) and therefore cool climate. Here, the susceptibility of cirrus clouds to the injection of ice nuclei in the upper troposphere is investigated in the extended Co...

Cardiovascular Diseases To the Editor: We read with interest the review by Nugent and Edelman.1 The authors have discussed seeding of prosthetic vascular graft but have not commented on the difference between single-stage and two-stage seeding. Single-stage seeding involves extraction of endothelial cells (ECs), coating of graft lumen, and implanting the graft into the patient, all within the t...

BACKGROUND/AIMS To review the effectiveness of intra-arterial chemotherapy for advanced intra-ocular retinoblastoma with vitreous and/or subretinal seeds in naive (untreated) and previously treated eyes. METHODS Retrospective study, approved by the institutional review board, of 76 eyes of 67 patients with retinoblastoma with subretinal and/or vitreous seeding treated with intra-arterial chem...
